ADJUSTABLE WIRE SCREEN.

Specification of Letters Patent.

Patented Feb. 19, 1907.

Application filed December 5.1905. Serial No. 290,499.

Be it known that we, ANDERs JOHAN \\'1K- Improvements in Adjustable WireScreens,

ot' which the following isa spec iication.

Our invention relates to wire screens, and especially to those intendedand adapted to be adjusted and more particularly to those adapted to berolled up.

'l hc objects oi' our invention are, iirst, to provide a strong,durable, ellicient, and inexpensive screen; second, to provide a screencapable ol' adjustment and of being contained in a small space; third,to provide means for adjustment easily and conveniently manipulated.\\'e attain these objects by the means and devices described hereafter,and illustrated in the accompanying drawings, in which like numbers ofreference rel'er to like parts throughout the various views.

Figure 1 is a front elevation of our screen and adjuncts. Fig. 2 is aplan view. Fig. 3 is a side elevation. Figs. 4 and 5 are enlarged viewsof various parts. Fig. is an elevation showing a modification of our in-Vention. Fig. 7 is a front elevation showing device shown in Fig. 6.Fig. 8 shows an enlarged detail of this modification. Fig. 9 is a sideelevation, Fig. 1t) is a front elevation, and Fig. 11 is an enlargeddetail of another modification. Fig. 12 shows still anothermodification.

1 represents any casing, such as that ot a' Window, door, or other spacewhere it is desired to set the screen. 1 may also be a separate casing,made especially for the screen and to which the latter is attached.

2 are the intermeshing and interlocking Wires constituting the screenitself. We preferably make these in the form of an oval helix.

3 are rings, placed at proper intervals, intermeshing with the wires 2of the screen and securing the latter to the pin-rod 4, runninglengthwise ol' the roller 5, which is preferably a pipe.

(i t5 are slots cut in the pipe .-3, in which the rings 3 lie. 'lheserings I en( irclc the pin t within the pipe 7 7 are plugs titting thepipe end.

S is the shal't forming the center ol' the plug 7 and pipe 5 and runningin the bearings at. 26. On this is secured at one end toothed wheel 9,inwhich meshes the worm It) onthe shal't 11, operated by the sprocketl2.

I3 is a casing covering and containing the wheel 9, the worm lt), andother adjuncts, and sometimes we may construct it to cover the whole streen, as in Fig. l2.

14 is an angle-iron 'l'rame in which the screen 2 slides, though we donot limit ourselves to the use ol' anangle-irontrame. Itis evident thatwood or other material may be. as well employed. p

15 isa pin securing the plug T to the pipe 5.

1G is a bar or apron forming the bottom ol' the screen; 17 holes in thebar, into which the helix for-nung the lower margin otthe wire screen isinterloopcd, 1S, holes in bar and lower part ol` easing or l'rame bywhich they can be locked by the insertion oi' pins.

27 is a rope or chain t'or ope ating wheel 12.

19, Figs. 6 and S, is a disk adapted to be placed upon and iirmlysecured to the shaft S at each end and in place of the gear-wheel 9. 2t)is an opening in said disk adapted to hold the end of a spring 22,secured at the other end to the pin 21 in the. casing or frame.

'ln Figs. 9, 1t), and 11,123 is a band or tape, of steel or othersuitable material, passing over the roller '25 and about the shalt S, towhich it is attached atone end and having at the other end the spring24. (Shown here only in part.)

Figs. 3, 6, 7, 9, and 1t) have the casing broken away in order to showthe various operating parts.

The construction and operation of' our dcvice is as follows: Theangle-iron or wooden frame 14 with the casing 13 13L may be attached tothe frame 1 of an aperture, such as a door or window. Sometimes we makethe casing 13u extend the l'ull length of the roller, so as to almostentirely inclose it, i'or protection and concealment. The plugs 7 withthe shafts 8 are inserted in the tube 5, the plugs o near each the IOO

held securely by the pins 15 and the shafts running 1n bearings on ythecasing 13. The screen 2, suspended on the roller 5 by the rings 3 lyingin the slots 6 and in turn held by i the rod Ll, is adapted to be rolledup by means ol' the sprocket and shaft 11 112 operating the I, worin l()and gear-wheel 9, attached to the shalt h at one end ol' the roller 5,and 1n turn operated. il' desired, by a chain or rope 27.

By ma king our screen of mterlocked or 1nterineshed wire helices We areenabled to. proyide a strong yet flexible fabric, and by making thehelices of ellipticalform the screen is thinner, lies better upon theroller-tube 5,

and the wires are less likely to become displaced.

The bar 16, forming the bottom of thel screen, slides in the angle-ironframe 14.

As shown 1n Figs. 6, 7, 8, 9, 10, and 11, We

ma y dispense with the worm-and-gear adjustment and use a spring, bywhich the screen is rolled up upon releasing the means for securing ityin place. These means may be pins inserted in the holes 18 or any othersuitable means. The spring shown in Figs. 6, 7, and h is a coil-spring,so attached one at each end ol` the roller 5, as before shown, as torotate the roller, and thus roll up the screen. In some cases we mayprefer to use a tapeor band 23, secured to and rolled around the shal'tN and passing over the roller 25, .being secured to a stronghelicalspring 24, bywhich tension is applied to the tape and the roller 5rotated. We do not limit ourselves to these l'orins of adjustment, asother forms may be utilized t.) accomplish the same end.

What we claim, and desire to secure by Letters Patent, isl 1. Thecombination of an angle-iron frame adapted to partially inclose theedges of a screen, a casing superimposed upon the i'rame'and adapted tosupport and cover a roller, a roller comprising a tube, a shaft and plugsecured in each end thereof and adapted to run in bearings in thecasing, a plurality oi' rings lying in apertures in the roller engaginga rod extending longitudinally through the roller, and engaging on theoutside a screen composed of a plurality of intermeshed helices havingasash at the bottom, a worm-and-gear adjustment at one end of the roller,covered by the casing and by means of which the roller may be rotatedand th screen rolled up or down.

' 2. rlhe combination of an inclosed casing l a roller within theeasing; a screen formed of a plurality of intermeshed helices; aplurality i of rings lying in slots in the roller and engaging the upperhelix, a rod extending longitul dinally within the roller and engagingthe l rings, a channel-guide in which the screen slides, and means forra sing and lowering 1 the screen. 3 3. The combination of an inclosedcasing; l a screen-guide beneath the. same; a roller f within thecasing; a screen formed of a. plurality of intermeshed helices; a rodextending "longitudinally within the roller, a plurality i of ringslying in openings in the roller, and l engaging both the screen and therod. l, 4. The combination of a tubular roller; a plurality of ringslying in apertures in the roller; a screen l'orined of a plurality ofintermeshing helices engaging said rings, and a rod extendinglongitudinally within the roller and engaging said rings. y

5. The combination ofV a tubular roller; a longitudinal rod within theroller a screen formed 4of a pluralty of intermeshed helices, and aplurality'of rings lying in apertures in 6. The combination of a tubularroller, having a plurality of transverse slots cut therein 5 a rodextending longitudinally inside cf the roller a plurality of rings inthe slots engaging said rod and a screen engaged by said rings on theoutside of the said roller.

7. The combination of a tubular roller having slots therein; rings lyingin the slots 5 a pin Within the roller, and a screen outside the rollerboth engaged by the rings.

8. A roller; a screen formed of a plurality of intermeshed helices g apin running longitudinally within the roller, and a plurality of ringsen aging both the screen and the pin.
